# Mailer

To access this menu, navigate to **Administration** > **Workspace** > **Mailer**.

* Use the **`From`** field to set the address to send the email.
* Check the **Dry Run** option to send the email only to the address defined in **`From`**.
* You can also filter who receives the email by using a valid user query in the **`Query`** field.
* Then, you can write a subject and a body for the email. When you write the body, add brackets to add dynamic data to the body. Add the following brackets to the email body:
  * `[unsubscribe]`: creates an unsubscribe link. The email body **must** have an unsubscribe link.
  * `[name]`: uses the full name of the user that receives the email
  * `[fname]`: uses the first name of the user that receives the email
  * `[lname]`: uses the last name of the user that receives the email
  * `[email]`: uses the email address of the user that receives the email
